Our Riley has come soooo far over the last 6 books, and I loved this 6th book because of the significant character and relationship development overall. Also for the gore and suspense and smex that make this series so good. I love how the dynamic between Riley and the cow (Sal) and Cole are evolving. It was good to see the Shadow aka Ben and learning more about him. Aaaand of course the reunion with Quinn after they've had time apart. 5 stars.
